Just in case you haven't had your fill of PSY's viral K-POP sensation, the researchers at Virginia Tech's Robotics and Mechanisms Laboratory (RoMeLa) have put out a new video of their robot dancing Gangnam Style. While the robot named CHARLI-2 doesn't display any fancy footwork in the video, some of its walking and balancing technology is being implemented in the Navy's Autonomous Shipboard Humanoid (ASH).
